Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Polycrystalline thin film solar cells based on CuInGaSe2 (CIGS) and CdTe as absorber layers have been developed with efficiencies 15% using CdS as the buffer layer. However, the usage of CdS in these devices is harmful to the environment and has the potential to cause the manufacture problems due to the toxicity of Cd . Further, the collection efficiency of these solar cells is limited due to the narrow band gap of CdS (2.42 eV). Therefore, in order to improve the collection efficiency, to enhance the feasibility of manufacturing and to avoid environmental problems, it is desirable to replace CdS with a wide band gap material with appropriate properties. In this direction, novel materials have been proposed to replace the conventional CdS and In2S3 is one of the prominent alternatives. In this study, In2S3 films were grown by close spaced evaporation. The physical and chemical properties were investigated in relation to substrate temperature, film thickness and annealing in order to study the behavior of these films for their application as a buffer layer in solar cells. 132 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Energy plays a vital role in the development of any country. In the context of energy crisis in recent years, solar energy is one of the prominent renewable energy sources that can play a vital role in the energy sector in the coming future. Although crystalline solar cells have shown high efficiencies, solar cells developed using thin films offer many advantages over the crystalline counter parts. Although the existing polycrystalline thin film solar cells based on CdTe and CuInGaSe2 are giving good efficiencies and are commercially available in the market, however, they involve materials that are toxic or rarely available in earth's crust. Hence, investigations on novel and new materials that are abundant, less toxic and environmentally safe to handle with better properties are important. In this direction, Sn and S are two elements that exist in stable form, suitable for solar cell application. This book deals with synthesis of Sn-S films by a simple and economic technique, chemical bath deposition, followed by discussion of results on the analysis of these layers. SnS2/SnS heterojunction solar cell was developed to demonstrate the photovoltaic potential of this structure. 200 pp. Englisch.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The most popular polycrystalline thin film solar cells such as CdTe and Cu(In, Ga)Se2 showed high photovoltaic conversion efficiencies of 22.1% and 22.6%, respectively. However, the aforementioned absorber layers contain scarce (In, Ga, Se, and Te) and highly toxic (Cd, Se, and Te) elements which limit their future prospects. Due to this, researchers developed a new and promising absorber material, Cu2ZnSnS4 (CZTS), but the deposition of single-phase CZTS thin films is difficult due to its complex structure. In addition, suppression and detection of secondary phases (Cu-S, Zn-S, Sn-S, and Cu-Sn-S) in CZTS thin films are critical challenges. To solve this problem, growth on an alternative absorber layer is needed for the preparation of solar cells. Keeping the above research areas in mind, we conducted considerable research on the preparation of Cu-Sn-S layers using a two-stage process, characterization and tuning the structural, optical, and electrical properties of the Cu2SnS3 layers. More importantly, XRD, Raman, EDAX, SIMS, SEM, AFM, UV-Vis-NIR spectrophotometer, and Hall Effect characterizations revealed the suitability of Monoclinic Cu2SnS3 for solar cell device application.…
